EthereumKit

EthereumKit is a Swift framework that enables you to create Ethereum wallet and use it in your app.

// BIP39: Generate seed and mnemonic sentence.



let mnemonic = Mnemonic.create()

let seed = Mnemonic.createSeed(mnemonic: mnemonic)



// BIP32: Key derivation and address generation



let wallet = try! Wallet(seed: seed, network: .main)



// Send some ether



let rawTransaction = RawTransaction(

    ether: try! Converter.toWei(ether: "0.00001"), 

    to: address, 

    gasPrice: Converter.toWei(GWei: 10), 

    gasLimit: 21000, 

    nonce: 0

)



let tx = try! wallet.signTransaction(rawTransaction)

geth.sendRawTransaction(rawTransaction: tx) { result in 

    // Do something...
